When looking at PCIe NIC based systems performance can be assessed using the ODP PCIe optimised implementation (odp-dpdk, or the generic reference implementation odp-linux can be used, this implementation is not optimised for a specific platform.

Some representative numbers that use the OpenFastPath TCP stack and the fpm_burstmode test are shown here for a 40Gbps NIC.

  • with odp-dpdk scaling can be seen to be quite liner out to twelve cores

  • with the odp-linux reference implementation scaling is again good with  a lower overall throughput
